Which would you most expect to be an unstable atom?
Any atom in the first family of the periodic table of elements is very unstable.
What word means unstable elements that decay?
The word Radioactive usually denotes a substance containing unstable atomic nuclei.
What aspects of the composition of a nucleus can cause it to be unstable?
The two aspects that cause the nucleus of any element atom to be unstable are:not have the specific neutron/proton ratio to be a stable nucleus, and orhaving number of protons that exceeds the stability limit (exceeding 83).Referring to question below for more information.
Does neon have an electrical charge?
The nucleus of any atom, no matter what the element, is positively charged, because protons are positively charged and neutrons have no charge at all. The electrons orbiting that nucleus are what counteract that positive charge of the nucleus to give the atom as a whole an overall charge of zero.
Why are elements fe and s considered unstable atoms?
Iron (Fe) and Sulphur (S) are no more unstable than any other non-radioactive elements.
Which would you most expect to be an unstable atom?
Any atom in the first family of the periodic table of elements is very unstable.
What is a zirconocene?
A zirconocene is any of a class of metallocenes, containing a zirconium atom.
What is a zincin?
A zincin is any of a group of metalloproteases containing a zinc atom.
Why inner shells of atom are called kernel?
The correct term is nucleus, situated in the center of any atom and containing protons and neutrons.
What happens to the reactivity of any atom or ion that acquires the same electronic structure as an inert gas?
any atom that has or acquires a valence shell containing exactly eight electrons often is or becomes quite inert.
What is an acyl iodide?
An acyl iodide is any organic compound containing an acyl functional group directly attached to an iodine atom.
What word means unstable elements that decay?
The word Radioactive usually denotes a substance containing unstable atomic nuclei.
What is the simpest atom?
The simplest atom would arguable be hydrogen, containing just one proton and one electron. There are other hydrogen atoms, known as isotopes, all of which contain nuetrons. Hydrogen 1 is known as protium, or normal hydrogen. H-2 is dueterium with one proton, one nuetron and one electron. H-3 is tritium. Any isotopes above H-3 are highly unstable and exist for fractions of a second.
What is an arsinine?
An arsinine is any of a class of aromatic heterocyclic compounds containing a ring of five carbon atoms and an arsenic atom - the simplest example being C5H5As.
What aspects of the composition of a nucleus can cause it to be unstable?
The two aspects that cause the nucleus of any element atom to be unstable are:not have the specific neutron/proton ratio to be a stable nucleus, and orhaving number of protons that exceeds the stability limit (exceeding 83).Referring to question below for more information.
If an object if in unstable equilibrium any displacement will?
If an object is in a state of unstable equilibrium, any displacement will lower that objects center of gravity.
How positive and negative attract?
Think about it in science. If you had any atom with only positive charges or just negative charges it is an unstable atom, therfore you can't make anything out of it. They attract like puzzle pieces. To stabalize an object you need an equal amount of positive and negative charges.
